House
A "house" is essentially a container -- for a person, a family, several families or even a large group with shared interests (think of the term "houses of worship.") In the Bible, a "house" is also a container, but for spiritual things rather than natural things. In various uses a "house" can represent part of the mind, the whole mind, a whole person or even a church. The other nuance to the word "house" is that it is generally used in regards to our affections and desires rather than our thoughts and principles. This makes sense; we tend to engage our thoughts and rationality when we are out in the world doing our work, but when we are inside our houses we are driven most by love for our families and the desire to be good to those we love. So "house" tends to represent the things we want and care about -- which are ultimately the things that define us.
Arcana Coelestia # 10055
10055. 'A fire offering to Jehovah' means all things springing from Divine Love. This is clear from the meaning of 'a fire offering to Jehovah' as that which springs from Divine Love; for 'fire' in the Word means love in both senses, and when used in reference to Jehovah or the Lord it means Divine Love. For the meaning of 'fire' as love in both senses, see 4906, 5215, 6314, 7324; and for its meaning - in the highest sense, in which Jehovah or the Lord is the subject - as Divine Love, 6832, 6834, 6849. A burnt offering is called 'a fire offering to Jehovah' because when the Divine took on the Human, from that Human fought against and subdued the hells, and at the same time united it to the Divine, in order to save the human race, He did so out of pure love. That uniting is meant by a burnt offering, see 10042, 10053.
